  • This salt is designated "form 1" in Table 4.
  • the final product (HCl "form 2") was not the same crystal form as the starting material, as evaluated by PXRD (not shown). DSC and TGA measurements on the HCl form 2 salt indicated a monohydrate with a melting point of about 284 °C. TGA found 3.8% weight loss.
  • the HCl form 2 salt was also evaluated by DMSG, but using a 0 ⁇ 81 ⁇ 0% relative humidity profile ( Figure 10B ). The form 2 salt was relatively non-hygroscopic and showed no significant hysteresis.
  • the L-malate salt was of poor crystallinity (PXRD not shown). The sample melted at about 182 °C; however, additional thermal events occurred at about 95 °C.
  • the initial maleate salt was only of fair crystallinity, exhibiting a unique PXRD pattern and having a melting point of about 181 °C. This material was hygroscopic, having a moisture uptake of about 9% at 80% relative humidity. This salt is believed to be polymorph Form 5 or a mixture of Form 5 with one ore more other polymorphs, but this was not verified.
  • a second maleate salt sample having good crystallinity and characterized as polymorph Form 2 was subsequently tested, and the results from this polymorph Form 2 sample are shown in Table 4.
  • the L-tartrate salt was of poor crystallinity (PXRD not shown).
  • the sample melted at about 191 °C.
  • the tosylate salt was of fair crystallinity (PXRD not shown).
  • the sample melted at about 190 °C. Uptake of about 2.5% water was observed at about 65% relative humidity, with subsequent loss at about 30% relative humidity. This weight change was approximately equal to 1 mole of water.
  • the mandelate salt was of poor crystallinity (PXRD not shown).
  • the sample melted at about 224 °C.
  • the malonate salt was of poor crystallinity (PXRD not shown).
  • the maleate counterion assay was determined by ion exchange chromatography (IEC).
  • a suitable amount of the maleate salt is dissolved in water (Milli Q grade) and analyzed by IEC, and compared to calibration samples. Under these conditions, the peak due to maleic acid has a retention time of about 11 minutes.
  • the amounts of impurities and degradation products were determined by HPLC, using a Perkin Elmer LC 200 system with a diode array detector.
  • the analytical column was a Waters Xterra RP18, 5 ⁇ m, 250 x 4.6 mm, and the guard column was a Waters Xterra RP18, 5 ⁇ m, 20 x 3.9 mm.
  • Mobile phase A was a mixture of 90% 0.05 M ammonium acetate buffer at pH 5.5 and 10% acetonitrile.
  • Mobile phase B was a mixture of 10% 0.06 M ammonium acetate buffer at pH 6.5 and 90% acetonitrile.
  • the solvent gradient is shown in Table 5.
  • Enantiomeric purity was determined by HPLC, using a Chiralpak AD analytical column, 10 ⁇ m, 260 x 4.6 mm (Dalcel Chemical Industries, Ltd.) using an oven temperature of 30 °C, a mobile phase of 2-propanol/heptane/diethylamine (50/50/0.1), an isocratic elution mode, a flow rate of 0.5 mL/min, injection volume of 50 ⁇ L, detector wavelength of 265 nm, dilution solvent 2-propanol/heptane (60/50) and a sample concentration of 0.3 mg/mL. Under these conditions, the S isomer has a retention time of about 15.5 minutes, and the R isomer has a retention time of about 22 minutes.
  • Water content was determined according to USP 25, ⁇ 921>, Method ic.
  • Crystal form stability was assessed for samples of 5-[(Z)-(5-fluoro-2-oxo-1,2-dihydro-3H-indol-3-ylidene)methyl]-N-[(2S)-2-hydroxy-3-morpholin-4-ylpropyl]-2,4-dimethyl-1H-pyrrole-3-carboxamide maleate salt, polymorph Form 1, polymorph Form 2, and a mixture of polymorph Form 1 and Form 2.
  • a sample of the substance was placed into a controlled temperature and humidity stability chamber at 40 °C and 75% relative humidity. Samples were taken several times during the duration of the test and analyzed for qualitative changes in the PXRD patterns.
  • the duration of the test was 163 days, and no crystal form changes were observed in the PXRD pattern.
  • the duration of the test was 134 days, and no crystal form changes were observed in the PXRD pattern.
  • the duration of the test was 6 weeks, and no crystal form changes were observed in the PXRD pattern.
  • the percent recovery was calculated based on the average response factor obtained from a reference standard throughout the HPLC run, and considering the E isomer as the compound and not as an impurity. Compounds in this class exhibit reversible E-Z isomerization, with the Z-isomer generally favored. The isomerization is often an artifact of sample preparation and analysis. Thermogravimetric analysis (TGA) showed minimal water content, and it was not considered in the percent recovery calculation. The values shown in the table are averages of several injections.
  • N,O-dealkylation metabolite has been confirmed via nuclear magnetic resonance (NMR). This metabolite has biochemical, but not cellular, activity, suggesting that it lacks adequate permeability to enter cells.
  • the morpholinyl lactam metabolite is the product of oxygenation-dehydrogenation and has also been confirmed via NMR.
  • the morpholinyl hemi-aminal metabolite is an unstable metabolite identified via an iminium-ion trapping experiment. Metabolites were also determined in human urine, following a single 12.5 mg dose; these metabolites are shown in Figure 9 . Relative abundance was determined by UV response at 428 nm.
